This application claims the benefit of U.S. Provisional Application No. 60/988,394, filed on Nov. 15, 2007 and entitled “Soothing device” the contents of which are incorporated herein by reference.
1. Field of the Invention
The present invention relates to a baby soothing device, and more specifically, to a baby soothing device capable of moving upward and downward.
2. Description of the Prior Art
A common baby cradle can swing leftward and rightward or forward and backward via a swing mechanism. Thus, a baby care giver may push the baby cradle to swing back and forth for helping the baby fall asleep. However, the said swing mechanism may limit direction of the motion the baby cradle. As mentioned above, the baby cradle in the prior art may simply swing leftward and rightward or forward and backward. If the baby cradle needs to be moved upward and downward, it is necessary for the baby care giver to push the baby cradle with his hands or for a baby disposed therein to jump upward and downward on the swing device. In other words, the baby cradles capable of moving upward and downward are not available so far.
The present invention provides a baby soothing device comprising a holding structure for holding a baby; a supporting frame for supporting the holding structure on a surface; a sliding shaft having an end connected to the holding structure; and a driving device disposed between the sliding shaft and the supporting frame, the driving device being used for driving the sliding shaft to move upward and downward relative to the supporting frame.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
Please refer to
More detailed description for the driving device 22 is provided as follows. Please refer to
More detailed description for the baby soothing device 10 is provided as follows. Please refer to
In the embodiments based on the present invention, the method for driving the sliding shaft 20 is not limited to the said method. For example, structural design of the driving device 22 may be changed from the said active linkage mechanism (i.e. assembly of the said control panel, the motor, the driven gear, the driving rod, the torsion spring, and the rotating part) to a simple elastic part design. That is to say, instead of utilizing the motor 38 to drive the sliding shaft 20, the driving device 22 may only utilize the elastic part 40 (such as a spring) to sheath the sliding shaft 20 and to abut against the sliding shaft 20 and the positioning sheath 18 at two ends respectively. In such a manner, when the user wants to make the baby soothing device 10 move upward and downward, the user simply needs to pull the arm 29 downward (at this time, the elastic part 40 is in a compressed state), and then releases the arm 29. Such the sliding shaft 20 starts to slide along the positioning sheath 18 back and forth by the elastic force provided from the elastic part 40 so that the holding structure 12 may move upward and downward correspondingly. In other words, the mechanism design of the baby soothing device 10 is changed from a motorized design to a manual design. As for which design is utilized, it depends on practical application needs. In addition, besides the said spring driving mechanism, the driving device 22 may also utilize other driving mechanisms, such as a pneumatic mechanism, a hydraulic mechanism, a magnetic mechanism, and so on. Furthermore, in said manual design embodiment, structural design of the guiding slot 44 may be not limited to said linear design. For example, the guiding slot 44 may also be a helix-shaped guiding slot. Thus, the motion track of the sliding shaft 20 in the positioning sheath 18 may be changed from the said linear track to a helical track via engagement of the protruding portion 46 of the sliding shaft 20 and the guiding slot 44 of the positioning sheath 18. That is to say, the holding structure 12 may also rotate relative to the connecting structure 27 while the holding structure 12 is moving upward and downward.
Compared with the prior art, in which a swing mechanism is utilized to make a baby cradle swing forward and backward or leftward and rightward, the baby soothing device provided by the present invention utilizes an active linkage mechanism (e.g. assembly of the said control panel, the motor, the driven gear, the driving rod, the torsion spring, and the rotating part) or a manual spring mechanism to drive a holding structure for holding a baby to move upward and downward. Thus, the baby soothing device of the present invention may have more variety in direction of motion.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
